Popcount hardware
WebWe add extra instructions to the ISA in an effort to get more speed. Popcount as I mentioned earlier, can be easily done in a naive way by cascading a bunch of adders on the input, at the cost of gate count (space you could use for things like more powerful general-purpose execution units) and a long critical path through those adders. WebIt is an advanced, variable instruction length, Very Long Instruction Word (VLIW) processor architecture with hardware multi -threading.
